One millionth of a day platform

The one millionth day platform is a specially designed basic supporting experimental equipment with strong shock absorption effect for experiments with high precision requirements and anti-interference. It can control the interference during the vibration of various devices, resist the interference during the friction vibration between road vehicles and the ground, resist the interference during the natural movement of the earth, and resist the interference during natural weather changes; Ensure accuracy during the experimental process. The Tian platform is designed with three-level shock absorption
characteristic
1. The countertop is made of high-quality natural marble countertop panel (100mm behind the panel), and the weight of the entire isolation platform is over 300kg;
2. Low natural frequency and ultra-high seismic isolation performance;
3. Using natural marble countertops with precision grinding and polishing on the surface, the darker color can effectively reduce stray light, making it suitable for various scientific experiments, especially for use on platforms.
4. The vibration isolation support adopts a composite of multiple materials for filling, solid damping vibration isolation, with less maintenance and adjustment work, and a stable and reliable structure
5. The countertop is acid and alkali resistant, with high corrosion resistance.
Technical Parameter
● Vibration isolation material: Damping materials are used above and below the support legs
Good stiffness, no deformation under load
Standard countertop, thickness 100mm
Flatness not exceeding 0.01~0.05mm
● Plane roughness: 0.8 μ m~1.6 μ m
The height of the tabletop from the ground is 800mm
The support legs are made of ultra synthetic materials inside, which increases the stability of the tabletop.
Specifications and dimensions: 900 * 600 * 800 (overall) with a tabletop thickness of 100mm
Material:
Tabletop: Made of black natural marble, with polished edges Adjustable range: -10 to+15mm
Support frame: 45 # steel electrostatic spraying frame: Made of Φ 80 × 80MM Shanghai Baosteel square steel, the surface has been treated with acid and alkali solution rust removal, phosphating, electrocoating, and epoxy resin spraying, with optional colors
Bottom: Made of ABS series;
Weight: 300kg
Instrument performance:
1) Flatness: 0.02~0.05mm/600 × 600mm; 4 supports;
2) Natural frequency:<1.5-3Hz, related to the load and actual usage situation
3) Bracket: The overall welded four or six support structure has better rigidity and stability. The pipe bracket is equipped with two sets of height (horizontal) adjustment mechanisms, and the total height of the table and bracket is 800mm. The support bracket is filled with cement and high-density materials, and the processing technology is relatively complex, which greatly increases the stability and anti-interference ability of the bracket.
4) The support point of the pressure bearing is adjustable,
5) The overall tabletop has three-level seismic isolation performance
